There’s a whole bunch of quotes, symbols, titles and historical events like these which have prompted the same bizarre I’m-now-questioning-the-entire-universe response.

In recent years it’s been deemed the “Mandela Effect”, and a growing cult of believers on the internet have taken the phenomenon a step further.

What is the ‘Mandela Effect’?

In 2010, a paranormal enthusiast named Fiona Broome claimed she remembered the news coverage of Nelson Mandela’s tragic death in a South African prison during the 1980s.

When she shared this thought with a group of people, many of them said they remembered this event taking place, or learnt about it in school.

Only that never happened. Mandela was alive at the time they apparently vividly recalled this.

He died in December 2013, three years after Broome first voiced her theory, while suffering from a prolonged respiratory infection at his home in Houghton, Johannesburg.
